1. 'Mayonaise'

"Mayonaise" – yes, it is officially spelled incorrectly, deal with it – won this poll by a significant margin. It's easy to understand why. The melody is straight-up lovely, and Billy Corgan achieves a balance of distinct noise and traditionally beautiful guitar playing in this song unmatched by anything else in his catalog. In some ways, it's the ultimate Smashing Pumpkins song.
